Abstract

L'invention concerne un dispositif électronique capable de détecter un objet externe au moyen d'un capteur de proximité tandis qu'une image de prévisualisation est affichée à l'intérieur d'un dispositif d'affichage au moyen d'une première caméra. Le dispositif électronique peut afficher, sur la base de la détection de l'objet externe, l'image de prévisualisation à l'intérieur du dispositif d'affichage au moyen d'une seconde caméra disposée sur une surface du dispositif électronique sur laquelle la première caméra est agencée, et générer un son relativement faible par rapport au son généré lorsque la première caméra est actionnée.
